because submit method requires this parameter in UNIX timestamp. But we are passing milliseconds. If somebody could fix the source and produce new jar file of plugin, I'll be very happy since I'm not familiar with Java at all

it's working fine now, but I got troubles to sync the playback with the registration, due to the nature of the streaming (it's really hard to detect the end of a song played on the ps3, on the server side). RIght now, one time playback means I've listened to the tracks 3 times on the last.fm site :\

Hm.. for me it scrobbles fine. One entry for one listen. I've tried with about 30 tracks on different days (mp3 and FLAC transcoding both fine). But another question is why on last.fm page it displays: "Listening now using XMMS2-Scrobbler". I don't have XMMS2 running on my machine. But last time before listening with PMS I was listening with XMMS2 from another machine. Looks like last.fm remembers last program name that user was using. So, PMS should send own identification string.
